Allow ampli status to detect usage in strings

## Summary

I am using Next JS with `@amplitude/analytics-browser` and there are some cases where I want to log an event from the server. To accomplish this I have a component that calls an event on the client

``

This works fine, but my only issue is that when running `ampli status` the usage is not detected.

## Motivations

`ampli status` allows me to make sure I have implemented all the required events, without tracking string usages the data is incomplete.
